Filed Jun 21, 2022 · Engine · CO

I was driving on the highway just reaching 55 mph, that is when all of a sudden, my suv stalled out with no warning no sound nothing. I tried to restart it and sounded as if it was trying to start but wouldn't. after a couple of times of trying that is when a tow truck came and as he was putting my suv on the flat bed I noticed huge amount oil on the ground. I got it towed to Chevy dealership for service and that is when they told me that the 6th cylinder cracked also a rod went through causing a hole in the engine block. I asked what could have caused it, because I'm on top of my maintenance and my suv only had 94,000 miles on it. That is when he explained to me that it was nothing that I did and that there was nothing that I could've done to prevent it and that there was nothing I did wrong that caused it. So, the leaves me asking, isn't that a manufacturing issue?

The exhaust manifold in my 2008 chevy trailblazer has broken now three times. The chevy dealer has changed the manifold twice for free but now they no longer want to pay for it plus I asked if they have made a change to the cast iron manifold and they tell me the part number changed in 2011 but my failures have occurred since then so I know the replacement manifold I will have the same problem. Exhaust fumes in winter enter the cabin.

Engine dies while driving (losing propulsion, steering, brakes, etc.) and the key will not restart when turned forward (in neutral), while coasting, but will restart when the key is turned back and then forward again. In this case, coasting down and braking and turning right, possibly with right turn signal on. Died right before starting to turn the steering wheel at about 15-20 MPH. It was a clear dry 100 degree afternoon, on smooth pavement. We live on a bumpy dirt road that is just over a quarter of a mile long to reach our house. Similar to other gm ignition key / no air bag recall programs for similar model year vehicles, such as the hhr. There is no recall, but how many people does this happen to? Any deaths, yet? I don't believe the air bags may have worked, should we have been involved in an accident. There was no information shown in the diver information center display (dic) and there were warning lights on in the dashboard, to indicate that the power was on to the instrument cluster (ic), but that the motor was off. I could not select brakes and steering as being affected, but with no motor, there is no vacuum brake boosting going on, and no power steering either.

Numerous times I have driven this vehicle and it continues to do the same thing when I reach speeds of about 35 to 40 MPH it loses power, the tach. Even declines in it's reading. It's like someone is behind me with a rope, and stepping on their brakes, slowing me down. This happens when I'm going straight down a street, making no turns, and let it basically idle roll down the street. All the while, it is in gear, engine running, and in motion on a city street
